# Purpose: measure the impact of concurrency on BroIDS, tshark and ntopng
#        this is a wrapper script around "tools-run.sh"
# Date: 01-Aug-2017
# Dependencies: "tools_run.sh" script must exist in the PWD
#        dependencies of "tools_run.sh" must be satisfied
# Invocation: $./tools_concurrency.sh as non-root user
# Output: results in "concurrency.log"
